Increased consumption of dietary sodium may increase the risk for atopic dermatitis (AD), according to a study presented at the 2022 annual meeting of the Society for Investigative Dermatology. Morgan Ye, MPH, and colleagues examined the association in a US population-based cohort of 13,183 children and adults identified from the NHANES 1999- 2000, 2001-2002, and 2003-2004 cycles. The average dietary sodium intake was 3.30 grams, and 6% of participants reported current dermatitis at the time of the survey, while 12% of participants reported dermatitis in the previous year. A 1-gram increase in dietary sodium intake was associated with an increased risk for current dermatitis (aOR, 1.22; 95% CI, 1.02- 1.45) and a non-significant increase in the risk for dermatitis in the previous year (aOR, 1.15; 95% CI, 0.98-1.34), when adjusting for potential confounders like age, sex, ethnicity, and poverty income ratio.
